Question

after how many digits will the decimal expansion of 13 by 250 come to an end ​

Answer 1

Answer:

The decimal expansion of 13/250 will end after 3 decimal places

Step-by-step explanation:

250= 5×5×10

= 5^2 × 10

Therefore,

13/250 = 13/(5^2×10)

= (13×2^2)/ {(5×2)^2× 10}

= (13×4)/(100×10)

= 52/1000

= 0.052
